Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574060, here are decompositions:

13 + 31574047 = 31574060
19 + 31574041 = 31574060
61 + 31573999 = 31574060
103 + 31573957 = 31574060
229 + 31573831 = 31574060
241 + 31573819 = 31574060
307 + 31573753 = 31574060
313 + 31573747 = 31574060

Showing the first eight; more decompositions exist.
